MACHINE FOR FORMING WIRES FROM METAL DISKS OR PLATES.

SPECIFICATION forming part of Letters Patent No. 526,230, datedSeptember 18,1894.

Application filed December 4,1893. Serial No. 492,704. (No model.)

will be fully described hereinafter and then pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming part ofthis specification,

in which similar letters of reference indicate corresponding parts inall the figures.

Figure 1 is a plan view of the improvement. Fig. 2isa sectional sideelevation of the same on the line 22 of Fig. 1; and Fig. 3 is an endview of the drawing rollers and mechanism for operating the same.

The improved machine is provided with a suitably constructed bed A, onwhich is mounted to slide longitudinally the head B, in which isjournaled the vertically disposed shaft or arbor O, carrying at itsupperend a metallic disk D, from which the Wire or rod is to be formed.The edge of the disk D is adapted to be cut into a strip D by tworevoluble cutters E, E, located one above the other and adapted to cutthe periphery of the disk D into a strip as the disk is revolved and fedforward toward the revoluble cutters E E as hereinafter more fullydescribed. The strip D thus cut off from the periphery of the disk D ispassed between two drawing rollers F and F, which press the strip into arod or wire of any desired cross section, the said'wire being wound upon a spool G secured on a vertically disposed shaft G journaled in theouter end of an extension A of the bed A.

In order to give the necessary motion to the several parts, thefollowing devices are provided: On the lower end of the shaft 0 issecured a bevel gear wheel H in mesh with a bevel gear wheel H mountedto rotate in a suitable bearing B attached to the under side of the headB. The gear wheel H forms a nut screwing on a screw rod I, mounted torotate in suitable bearings in the bed A, as is plainly shown in Fig. 2,the outer end of the screw rod being provided with a crank arm I forconveniently turning the said screw rod to return the head B to itsoutermost position after the disk has been cut into a strip and a newdisk is placed on the shaft 0. Ordinarily, however, the screw rod I issedurely locked in place by a set screw I or other suitable means, sothat the screw rod does not revolve, and when the disk D is rotated alike motion is given to the shaft 0 and the gear wheels H, H, so thatthe latter travels forward on the screw rod I and carries the head Bwith the shaft 0 and disk D in the samedirection, as the edge of thedisk diminishes in size by the cutters E, E cutting ofi the stripfromits peripheral edge. The feed of the head B depends on the pitch of thethread on the screw rod I, which latter is changed according to thewidth of the strip to be cut from the peripheral edge of the disk D. Thecutters E, E are located one above the other and are secured on1ongitudinally extending shafts J, J respectively, mounted to rotate insuitable bearings attached to slides K, K respectively, held verticallyadjustable in suitable guide-ways formed in a frame A supported on oneend of the bed A. Screw rods K and K engage the slides K, K respectivelyand serve to adjust the said slides vertically so as to bring thecutting edges of the cutters E, E in proper position with relation toone another, so as to out the strip D properly from the disk D.

The outer ends of the shafts J, J carry bevel gear wheels J J 3respectively in mesh with like gear wheels J J 5 respectively, securedon a vertically disposed shaft J journaled at its upper end in bearingsattached to the frame A and at its lower end in bearings on the bed A.

On the extreme lower end of the shaft J 6 is secured a bevel gear wheelL, in mesh with a bevel gear wheel L, secured on atr'ansverselytransversely extending main shaft P journaled in suitablebearings on the bed A and its extension A. The extreme rear end of thisshaft P carries a bevel gear wheel 1? in mesh with a bevel gear wheel Psecured on the lower end of the shaft G carrying the spool G. On theshaft P is also secured a bevel gear wheel Q, see Figs. 1 and 3,.in meshwith a bevel gear wheel Q, fastened on the lower end of the shaft Qmounted to rotate in suitable bearings attached to a frame R carryingthe drawing rollers F, F, previously mentioned. On the shaft Q aresecured the bevel gear wheels Q Q in mesh with similar wheels F Frespectively, secured on the shafts F", F respectively, carrying thedrawing rollers F, F respectively. The shafts F, F are mounted to rotatein suitable bearings R held adj ustably in the frame B, so as to bringthe drawing rollers into proper relation with each other, and also topermit of conveniently changing the form of the drawing rollersaccording to the desired cross section to be given to the wire or rod.The drawing rollers F, F are formed with registering peripheral grooves,through which the. strip passes to be formed into the rod or wire of thedesired cross section. It is understood that the drawing rollers F, Fare located between the cutters E, E and the spool G, but if necessary,two or more sets of such drawing rollers may be employed to give thedesired shape to the strip cut from the disk D and also to exertsufficient pull on the strip to rotate the disk D, so as to permit thecutters E, E to cut the strip from the disk. It is understood that thepower of the drawing rollers thus serves to draw the edge of the diskbetween the cutters to permit the latter to cut the strip, at the sametime causing the disk D to revolve, so that the feed mechanism for thedisk is automatically actuated, as before described, and the disk isproportionately fed forward. It will be seen that by this arrangementthe disk D is cut into a continuous strip formed into a wire or rod ofany desired cross section.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1; In a wire or red forming machine, thecombination with a rotary spindle carrying a diskfrom which the wire orrod is to be formed, and cutters for cutting a strip from the said disk,of'drawing rollers between which the strip passes and by which the diskcarrying spindle is rotated, and a feed mechanism for feeding the diskto the cutters, said mechanism being operated by the rotary movement ofthe said spindle substantially as described.

2. In a wire or rod forming machine, the combination with a rotaryspindle carrying a disk from which the rod or wire is to be formed, androtary cutters for cutting a strip from the said disk, of drawing Irollers between which the strip passes and by which the disk carryingspindle is rotated, gearing for simultaneously operating the saiddrawing rollers and cutters, and a feed mechanism for feeding the diskto the cutters, said mechanism being operated by the rotary movement ofthe disk carrying spindle,substantially as described. v

3. In a wire or rod forming machine, the combination with the cutters,of a sliding head, a spindle mounted in said head and carrying a diskfrom which the wire or rod is to be formed, a gear wheel on the lowerend of the spindle, a screw rod adapted to be locked stationary, and agear wheel mounted in the sliding head and forming a nut through whichthe screw rod passes, substantially as described.

4. In a wire or rod forming machine, the combination with the cutters,of a sliding head, a spindle mounted in the head and carrying a diskfrom which the wire or rod is to be formed, a gear wheel on the lowerend of the spindle, a screw rod provided with acrank arm at one end,means for locking the screw rod stationary, and a gear wheel mounted inthe sliding head and forming a nut through which the screw rod passes,substantially as described.

5. In a wire or rod forming machine, the combination with a spindlemounted to rotate and adapted to carry the disk from which the wire orrod is to be formed, and a feed mechanism for the disk carrying spindle,of cutters for cutting a strip from. the disk, drawing rolls engagingthe cut strip to, press it into a wire or rod, a reel upon which thewire or rod is wound, and means for simultaneously operating thecutters, drawing rolls, and reel, mo substantially as described.

6. In a wire or rod forming machine, the combination with a main shaft,of cutters, drawing rolls, a reel, and gearing for operating the cuttersdrawing rolls, and reel from [05 the main shaft, substantially asdescribed.

7. In a wire or rod forming machine, the combination with a main shaft,of rotary cutters, drawing rollers, a reel, gearing for operating thecutters, drawing rollers, and reel no from the main shaft, a rotaryspindle carrying a disk from which a strip is to be cut to form the rodor wire, and a feed mechanism operated by the rotary movement of thesaid spindle, for feeding the disk to the cutters, 11.5 substantially asdescribed.
